%description
Bagged OutlierTrees is an explainable unsupervised outlier detection
method based on an ensemble implementation of the existing OutlierTree
procedure (Cortes, 2020). This implementation takes advantage of bootstrap
aggregating (bagging) to improve robustness by reducing the possible
masking effect and subsequent high variance (similarly to Isolation
Forest), hence the name "Bagged OutlierTrees". To learn more about the
base procedure OutlierTree (Cortes, 2020), please refer to
<arXiv:2001.00636>.
